Hi Mo,
I carefully roll out solid strand bare copper 6 or 8 gauge (overkill
but mechanically superior) along the racks and solder my own lugs on
the ends in line. The final product looks like a rod rather than a
wire running along the panels. I've also considered using a rod or
bar, but If your careful how you roll out the solid strand it looks
really neat and wire is much easier to obtain and transport. On a
larger job coming up, I'm considering prewiring the grounds with a
bar or rod or simply making up my solid Cu wires in advance.
Hope that helps,
Jeff
